Title:
PHOTOCURABLE ADHESIVE COMPOSITION, PHOTOCURABLE ADHESIVE LAYER, AND PHOTOCURABLE ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2010/140442
Kind Code:
A1
Abstract:
Provided are a photocurable adhesive composition, a photocurable adhesive layer, and a photocurable adhesive sheet with which it is possible to form an adhesive layer that has sufficient initial adhesive strength through the process of drying and cross-linking without having any adhesive protrude at normal temperatures and pressures, hardens easily with light irradiation, and has a high peeling resistance. The photocurable adhesive composition contains a graft polymer that graft-polymerizes a monomer containing a cyclic ether group to a (meth)acrylic polymer and and a cationic photopolymerization initiator. The photocurable adhesive layer and the photocurable adhesive sheet are prepared by using said photocurable adhesive composition.
